PROBLEM TO BE SOLVED: To reduce the size, the weight and the cost of a seat rail device without impairing the strength of the seat rail device for supporting a seat mounted on an automobile in a longitudinally movable manner. SOLUTION: In a seat rail device, an upper rail 1 is engaged and mounted on a lower rail 2 such that an upper bottom wall section 11 is located above a lower bottom wall section 21, and also such that an upper sloped wall section 16 is located within a lower groove 26 surrounded by a lower sidewall section 23, a lower top plate section 25, and a lower downwardly hanging section 27; a roller 31 is mounted and turnably supported between the lower bottom wall section 21 and the upper bottom wall section 11; an upper ball-shaped rolling body 33 is mounted and turnably supported in an upper in-groove space 26a partitioned and defined in the lower groove 26 by the upper sloped wall section 16; and a lower ball-shaped rolling body 35 is mounted and turnably supported in a lower in-groove space 26b.
